WRENCH.

Application filed August 26, 1915.

To all whom it may concern:

Be it known that 1, ANDREW J. SEYBERT, a citizen of the United States,residing at East Brady, in the county of Clarion and State ofPennsylvania, have invented certain new and useful Improvements inWrenches, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to certain new and useful improvements inwrenches and more particularly to what is known as oil well wrenchesadapted to be used for supporting and rotating drill and other toolsused in connection with oil wells. the object being to provide a wrenchwith a removable jaw mounted on rollers within a head in such a mannerthat the same will rotate freely.

Another object of my invention is to improve a construction of thisclass of wrench by providing a head with upwardly pro.- jecting ears towhich the arms of the lever are pivotally connected. in order to allowthe head to swing in respect to the lever.

Another object of my invention is to provide a' wrench. which isexceedingly cheap in construction, the jaw being mounted within the headin such a manner that the same can be readily removed in order to insertjaws of different shape if desired.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings :Figure 1 is a perspective view of my invention, Fig. 2is a section taken on line 22 of Fig. 1, and Fig. 3 is an inverted planview of the wrench.

Like numerals of reference refer to like parts in the several figuresofthe drawings.

In carrying out my invention I employ a ring shaped head member 1, whichis pro vided with a hexagonal depending flange 2, one side of which iscut away to form an opening as clearlyshown, said opening extendingthrough the ring portion. The ring portion 1 is provided with oppositelydisposed upwardly projecting ears 3, to which are pivotally connectedthe arms 4, of a forked lever 5, a pivotal connection being formed by abolt 6, as clearly shown, in order to allow the lever to be readilyattached or detached therefrom. The lever is provided with a bail 7, towhich a supporting cable is adapted to be connected in the well knownmanner. A. detachable han- Specification of Letters Patent.

the sides of the hexagon flange is .a pivot pin 10, on which is mounteda roller 11 forming a roller support for the lateral projecting flange12 of a jaw 13 which is formed with a depending flange 14, havingoppositely disposed lugs 15, provided with threaded sockets in whichhandle members 16 provided with threaded ends are detachably mounted,said handle members being arranged in a plane below the de- ,7

pending flange ofthe head in order to allow the same to be turned torotate the jaw 18.

The jaw 13 ,is secured in position within the head by washers,1-7,arranged on machine screws 18, working in threaded bores formed in thering 1 and it will be seen i by this. construction, the jaw is mountedupon rollers and held in position by wash ers' in such amanner that thejaw can be readily inserted or detached. The jaw is provided with adetachable jaw face 19 secured in position upon the jaw by machinescrews 20, working in threaded bores formed therein as shown in Fig. 2,whereby the face can be readily detached and any shaped jaw facesubstituted therefor so as to receive various shapes of tools or anyother article to be turned.

From the foregoing description it will be seen that I have provided anoil well wrench having a bifurcated head in which the jaw is revolublymounted upon rollers in such a manner that an exceedingly strong supportfor the jaw is formed and in such a manner that the jaw is free torotate when a drill or other tool has been placed within the jaw facethereof.

What I claim is 1. A wrench of the kind described, comprising a headmember having a hexagonal depending flange, one side of said flangebeing cut away to form an opening, pins extending through the othersides of said flange carrying rollers, and a jaw having a lateral flangemounted upon said rollers.

2. The combination with a head provided with upwardly projecting ears,of a lever provided with arms pivotally connected to said ears, rollerscarried by said head, and a jaw revolubly mounted upon said rollers.

8. In a wrench of the kind described, the combination with a head,having a six-sided depending flange, one of said sides being cut away toform an opening, stud pins eX- tending through the other side of saidflange, rollers mounted on the inner ends of said studs pins, a jawhaving a lateral flange mounted upon said rollers within said head,

means for holding said jaw in position therein, and a forked leverhaving pivotal connection with said head.

4. In a wrench of the kind described, the combination with a head, of aseries of rollers carried by said head, a jaw provided with a lateralflange revolubly mounted upon said rollers within said head, adetachable handle carried by said jaw in a plane below said head, meansfor securing said jaw within said head, and a lever having a pivotalconnection with said head.

5. In a wrench of the kind described, the combination with a ring shapedhead having a depending flange, of stud pins extending transverselythrough said flange, rollers mounted upon the inner ends of said studpins, a jaw provided with alateral flange arranged within said head andmounted upon said rollers, means for securing said jaw within said head,oppositely disposed ears formed on said ring, a forked lever having itsarms pivotally connected to said ears, anddhandles carried by said jawbelow said hea 6. In a wrench of the kind described, the combinationwith a forked lever having a detachable handle, of a head pivotallysupand a jaw revolubly mounted upon said rollers within said head.

'8. As a new article of manufacture, an oil well swivel wrench,comprising a ring shaped head having a hexagonal depending flange, oneside being cut away to form an opening, pins extending through the sidesof said flange, rollers mounted on the inner ends of said pins, a jawhaving a lateral flange revolubly mounted upon said rollers, said jawhaving an annular depending flange provided with oppositely disposedlugs, handles carried by said lugs, means for securing said pivotalconnection with said head.

9. An oil well wrench, comprising a head having upwardly projectingears, a lever having arms pivotally connected to said ears, rollerscarried by said head, a jaw revolubly mounted upon said rollers, handlescarried by said jaw in a plane below said head, and a detachable jawface mounted upon the top of said jaw.

In testimony whereof I hereunto afliX my signature in the presence oftwo witnesses.
